When Cupid and Psyche get married, at the end of their story in Apuleius' Metamorphoses VI.23, Jupiter announces that they will be wed iure civili:
Et ad Venerem collata facie, ‘Nec tu,’ inquit ‘filia, quicquam contristere, nec prosapiae tantae tuae statuque de matrimonio mortali metuas. Iam faxo nuptias non impares, sed legitimas et iure civili congruas.’
The gods have arranged this marriage and made it be. So why does Jupiter say he will make it "in accordance with civil law"? What does the term mean in this context? Why would the gods care about something regarding civilian laws—or what sense of civilis should we be thinking of to understand this passage? Is it a joke (just like the passage elsewhere where Apuleius says the Greeks in his story spoke Latin)?
